Review of the ground beetle subgenus Micronialoe from Korea, with a description of a new species (Coleoptera: Carabidae: Pterostichus)

초록

Micronialoe (Pterostichini: Pterostichus) is a poorly known subgenus of the ground beetle genus Pterostichus, which includes three species from the Korean Peninsula and adjacent islands. Here, a new species, Pterostichus (Micronialoe) spinulosus sp. nov., was identified among the specimens collected from Mt. Biseulsan and Mt. Choejeongsan, Daegusi, Korea. Along with the description of the new species, all Korean species are redescribed, and the subgenus is re- diagnosed. The new species is morphologically allied to P. (M.) bifoveolatus, thus, the intraspecific variation of the new species is examined and valid characters for distinguishing species are discussed. A key for the identification of the species of the subgenus is also provided.
